FLUSHING-TANK. v

Specification of Letters Patent.

Patented Jan. 5, 1909.,

Application led February 17, 1906. Serial No. 301,622.

To all 'whom it 'may-camera:

Be it known that'I, JOHN HEALD, a citizen of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented a new and useful Improvement in Flushing-Tanks, of which the following, taken in connection with the accompanying drawings, is a full, clear` and exact escription.

The invention relates ingeneral to rece tacles for containing liquids, and particular y to iiushing-tanks for water-closets; and the object of my invention is to provide a iiushing tank in which all sweating is prevented, even in an all-metal construction.

It is customary to provide flushing tanks with a metallic lining, usually composed of lead, zinc or copper, placed within a wooden casing, the latter being employed to prevent sweating. It is found, however, that in damp lavatories this does not prevent sweating of wood-cased tanks. On account ofthe sweating the all-metal construction has been The improvementconsidered impractical. entirely overcomes this tendency in the woodcased tanks, and also in the all-metal construction.

In the drawing, Figure 1 is a vertical sectional view of the ushing-tank at line Y, Y in Fig. 2. view at line X Xin Fig. 1.

Similar numerals refer to corresponding parts in the several views.

The numeral 1 indicates the outer casing of the tank, which is preferably made of metalbut may be of wood and not depart from my invention.

The numeral 2 indicates the inner lining or receptacle for holding liquid, which is made suiiiciently smaller than the case 1 to allow of a large air space 3 between them, both around the sides and at the bottom.

Air space 3 is accom lished by a stri) of corrugated sheet meta which gives alternating contacts as at 5 and 6 to casing 1 and lining 2. The strip of corrugated material 4 is preferably made of one continuous piece around the four sides of the tank and Isinclosed at the lower end b a cap 7 and at the ulpper end by a cap 8. lrower cap 7 braces t e lower end of the inner lining or receptacle 2 firmly in place and also stiil'ens corrugated sheet 4 and holds it in place. The upper cap 8 covers the upper end of corrugated piece 4 and on its inner side laps over the up- Fig. 2 is a horizontally sectional.

per edge 9 of lining 2, thereby holdiung the said lining and corrugated strip ir y in place and covering the air space 3 so that the liquid cannot enter same. Caps 7 and 8 fit so closely on to the corrugations of strip 4 that the whole strip is stifened and securely held in place so that it does not need a soldered attachment to lining 2 or the casing 1.

It is apparent that the dead air s ace 3 and corrugated strip 4 will prevent a sweating of the casing 1, whether 1t is made of wood or metal. This allows of the use of an allmetal construction which is highly preferable for eXtra damp lavatories where wood casings shrink and swell to such an extent as to entirely forbid their use.

A corrugated sheet 10 is placed in the bottom of casing 1 and the inner receptacle 2 rests upon the sheetyl() thereby giving an air-space 3 over the entire bottom of rece tacle 2 and casing 1, as shown in Fig. 1. T e corrugations in sheet 10 should be suiiiciently frequent at each end for the lower end of corrugated sheet 4 to rest upon.

I claim as new.

1. A tank composed of inner and outer receptacles, corrugated sheets of metal to separate said receptacles and form an air space between them, and means for closing the ends of said corrugated sheets to form nonconductive'dead air spaces for the sides and bottom of said tank, substantially as and for the purpose specified.

, 2. A tank composed of inner and outer receptacles separated by corrugated sheet metal to form an air space, and sheet metal ca s over the ends of said corrugations .to holjd them in form and close said space.

` 3. A tank comprising an outer casing 1 and an inner receptacle 2 having a space 3 between them, a sheet 10 of corrugated metal between the bottoms of said casing and receptacle, a sheet 4 of corrugated metal between the sides ofsaid casin and receptacle, a sheet metal cap 7 over the ower end of said corrugated sheet 4, and a ca 8 over the upper end of said corrugated siieet 4, substantially as and for the purpose specied.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
